The Essay on Errors, Uncertainties and Measurements
Abstract In this experiment, different measuring devices were used, namely the vernier calliper, micrometer calliper, foot rule, and the electronic gram balance. These devices were used to obtain the mean diameter, volume, mass, and the experimental value of density of the sphere of known composition. 1. Introduction Measurement is the process or act of determining the size, length, quantity, etc. ...
